Unable to change boot file on Cisco 3850

[whiteleyjl]

I was working on a Cisco 3850 24 port switch today and I read that it doesn't use the normal "boot system flash:XYZ.bin" but instead it's something like this:

"software install file flash:XYZ.bin new"

That changes the install package or something which makes it boot in the newly selected package which contains the new IOS.  Anyway, when i put in that command I get something about "Failed to ...." or something.  I'm sorry but I'm at home now and I don't have the device with me and it just occured to me to post this on the forum for possible help.  Either way, it's specifically says "Failed..." as the first word which is not what it should normally say.

I used these directions:

http://www.cisco.com/en/US/prod/collateral/switches/ps5718/ps12686/deployment_guide_c07-727067.html#wp9000169

I am in Install mode.  Can anyone help me figure out why this is happening before my outage window on Sunday night?  I've downloaded the new version of the IOS from Cisco.com and verified it is currently located in the flash of this device. 

Thanks for any help you can provide!

I searched high and low for a set of instructions to do this and found nothing.

Your post was perfect. Thank you.

Why can't I boot my switch with usbflash0?

Is there anything that can be done if the recovery bin is missing from sda9? I'm in the same situation where flash is read-only, the device won't boot and emergency-install is failing. I've even gotten a copy of the recovery bin from another device and tried setting RECOVERY_BUNDLE to point to the recovery bin on usb but it seems it doesn't actually do anything. Snips below:

---

The only way I could get around this issues is to do the set command.

like this example

switch#set BOOT flash: ios bin file

switch#reload
